C Correct answer
Explanation

The pattern alternates between division and multiplication with increasing factors: ÷2, ×1.5, ×2, ×2.5. Starting from 10, divide by 2 to get 5, then multiply 5 by 1.5 to get 7.5, then multiply by 2 to get 15, then multiply by 2.5 to get 37.5. Option C (5) fits this pattern perfectly.
